Incorrect Unexpected "}" when using \includegraphics

[MarcelRobitaille]

I am experiencing what I think is a bug where every time I use \includegraphics with a filename including =, I get Unexpected "}" for the closing brace after the file name.

This is fine:

\includegraphics[width=\linewidth]{./figures/a_filename-with_strange-symbols.pdf}

This gives the error, even though LaTeX itself has no problem displaying the figure:

\includegraphics[width=\linewidth]{./figures/a_filename-with_strange-symbols=.pdf}

I am using texlab 3.3.1. LSP client is Neovim 0.6.1.

I don't think so. I made a video of a working state, then I add the = and the error appears, I undo and the error goes away, I redo and the error reappears, I add a new line and the error is still there (after I go back to normal mode).

3.3.1 is the latest version in my distribution's repositories, but I can try installing from source.

Yeah, I thought it went away, but it reappeared. (I took it to be a standard "stale diagnostic issue", but it seems this is something different.)

Thanks for the report!

but it seems this is something different.

Yeah, this is not an issue with the diagnostics layer. Instead, it is a problem of the parser, which should be fixed with 867d5c1.

Thank you so much @pfoerster! I have installed from master and can confirm that this is fixing my issue.

I'm still getting this issue on 4.3.0, testing in neovim 0.8.0 on arch linux, even when compiling master from source. I thought maybe I had an old version of texlab knocking about that was being used instead but checked and this is the only version on my system. This bug occurs even in a .tex file where the only contents is \graphicspath{test} (it doesn't occur if there is no content or only spaces in the curly brackets).

Adding square brackets (as per the original example), e.g. \graphicspath[]{test} fixes the issue.

Edit: I misread this as this issue relates to \includegraphics, not \graphicspath. I'll open a new issue.

I'm getting a similar error with labels that contain the = symbol, e.g., \label{fig:x=2}.

Same error when using | to call shell commands
Example:
\input{|ipython scripts/test.ipynb}

Both of these errors should be fixed now :)
